我正在使用 Lex 制作一个带有语音操作的应用程序。我通过将 aar 文件添加到项目的 libs forler 并将这些行添加到 gradle 文件中来手动导入 lex 库。
compile(name:'aws-android-sdk-core-2.4.0',ext:'jar')
compile(name:'aws-android-sdk-lex-2.4.0',ext:'aar')
我通过添加从库中创建了麦克风组件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
tools:context="com.sample.app.MainActivity">
<com.amazonaws.mobileconnectors.lex.interactionkit.ui.InteractiveVoiceView xmlns:android="http://schemas.android.com/apk/res/android"
class = "com.sample.app"
android:layout_width="108dp"
android:layout_height="108dp"
android:layout_alignParentBottom="true"
android:layout_centerInParent="true"
android:background="@color/transparent"
android:id="@+id/voiceInterface" />
</RelativeLayout>
当我尝试运行该应用程序时，它给了我以下错误
